VBox/Virtualbox how to shrink VDI image and recover/reclaim unused disk space

VBoxManage modifyvdi /path/to/your.vdi compact

I believe this should be done only when your VM is powered off, but I decided to try it with the system powered on.  i wouldn't recommend it because it's dangerous even if it does work but this is a test system.  For anything important/production I would always take a backup first and make sure the system is powered off.

 VBoxManage modifyvdi XP-clone.vdi compact
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
